山东beplay全站app安卓加工产生时出现故障是什么表现?

  beplay全站app安卓失效由于塑料零件的表面是beplay全站app安卓型腔表面的复制品,如果beplay全站app安卓表面有表面缺陷如疤痕、腐蚀、微孔等,则将其复制到塑料零件的表面会导致光泽度差。如果空腔表面油腻、潮湿,破乳剂使用过多或不当选择,也会使塑料表面发黑。因此,beplay全站app安卓型腔的表面应具有良好的光洁度,更好使用抛光或镀铬的表面。腔体表面必须保持清洁,油渍和水渍应及时清除。脱模剂的种类和用量应适当。
  Mold failure because the surface of the plastic part is a replica of the surface of the mold cavity, if the surface of the mold has surface defects such as scars, corrosion, micropores, etc., copying them to the surface of the plastic part will lead to poor glossiness. If the surface of the cavity is greasy and wet, excessive use of demulsifier or improper selection will also make the plastic surface black. Therefore, the surface of the mold cavity should have a good finish, and it is better to use a polished or chrome plated surface. The cavity surface must be kept clean, and oil and water stains shall be removed in time. The type and dosage of release agent shall be appropriate.

  beplay全站app安卓温度对塑料制品的表面质量也有很大的影响。一般来说,不同类型的塑料在不同的beplay全站app安卓温度下,其表面光泽差异很大。beplay全站app安卓温度过高或过低都会造成光泽度差。如果beplay全站app安卓温度过低,熔体与型腔接触后立即凝固,这将降低型腔表面的再现性。为了增加光泽度,可以增加beplay全站app安卓温度。更好在beplay全站app安卓冷却回路中使用温水,以便在型腔内迅速传递热量,避免延长成型周期。该方法还可以减少beplay全站app安卓中的残余应力。另外,汽提坡过小,断面厚度过陡,肋部过厚,浇口、浇道截面过小或变化突然。乱流、beplay全站app安卓排气不良等beplay全站app安卓故障会影响塑件的表面质量,导致表面光泽度差。
  Mold temperature also has a great influence on the surface quality of plastic products. Generally speaking, the surface gloss of different types of plastics varies greatly under different mold temperatures. Too high or too low mold temperature will cause poor glossiness. If the mold temperature is too low, the melt solidifies immediately after contacting the cavity, which will reduce the reproducibility of the cavity surface. In order to increase the glossiness, the mold temperature can be increased. It is better to use warm water in the cooling circuit of the mould, so as to transfer heat rapidly in the mould cavity and avoid prolonging the forming cycle. The method can also reduce the residual stress in the die. In addition, the stripping slope is too small, the section thickness is too steep, the rib is too thick, and the section of gate and sprue is too small or changes suddenly. The surface quality of plastic parts will be affected by mold faults such as turbulent flow and poor mold exhaust, which will lead to poor surface gloss.
